Any chance we could see a chatroom implemented somehow? There are quite a few widgety type things that you could use, like Mibbit for example (Or Google Wave, hehe)
Open Source Game Development Forum & IRC
Free Software Games Blog & Planet
i was thinking about this feature for some time now. As i see it there are two options. A chat integrated into the site or an irc (web) chat. Both wouldn't need additional software (like xmpp) or registration (like google wave). Personally the irc solution is my favorite and i'am hoping for a channel at freenode, they say processing will take a l o n g time though.
Processing doesn't take that long (at least in my experience), heck, you can instantaneously create a channel and use it for ages before the staff take notice. There might be something I'm overlooking though.
